具体实施方式
下面结合附图和实施例对本申请作详细说明。可以理解的是，此处所描述的实施例用于解释本申请，而非对本申请的限定。图1是本申请实施例提供的一种音量调节方法的流程图，本实施例可适用于终端设备播放音源时对其音量进行调节的情况，该方法可以由本申请实施例提供的终端设备来执行，该终端设备的音量调节装置可采用软件和硬件中至少一种的方式实现，如图1所示，本实施例提供的方案包括步骤S101，步骤S102以及步骤S103。
在步骤S101中，当检测到终端设备进行音源播放时，获取所述音源的预设长度的音频信息。
终端设备可通过安装的第三方应用程序或系统自带的音视频播放软件进行音源的播放。其中，主要包括音源文件的获取、解码和输出等步骤。在一实施例中，获取到的音源文件可以是通过网络接收到的组播流，还可以是终端设备本地存储的音视频文件；获取到该音源文件后将其加载到内存缓冲区中；对加 载到内存缓冲区的音源文件进行解码，在解码开始之前，如果该音源文件同时包含有视频数据，需要进行音频数据和视频数据的分离，将分离后的音频数据输入至音频解码器，其中，音频解码器主要用于读取内存缓冲区中的音频数据，得到数字音频信号，并将该数字音频信号转换为模拟音频信号，终端设备的播放器件根据该模拟音频信号进行音频播放。在一实施例中，当监听到音源播放事件被触发时，确定终端设备开始播放音源，其中，该触发事件可以是检测到的触摸屏中显示的播放按钮被按下，还可以是检测到终端设备的播放器件如喇叭开始播放声音时，确定终端设备进行音源播放。
当检测到终端设备进行音源播放时，获取所述音源的预设长度的音频信息。在一实施例中，可对音频解码器解码得到的数字音频信号进行取样，确定该音源对应的音频信息，其中预设长度可以是3s、5s或10s等。在另一实施例中，还可以获取当前播放的音源的原始文件，通过对该原始文件的解析确定音源对应的预设长度的音频信息。在另一实施例中，以安卓(Android)系统为例，可通过android.media.MediaRecorder类或android.media.AudioRecord类获取音源的音频信息。
在步骤S102中，确定所述音频信息中的最大振幅和平均振幅。
振幅指物体震动过程中偏离原来位置的最大距离，人耳听到的声音的响度与音源的振幅相关，振幅越大响度越强。在一实施例中，可对音频解码器解码得到的数字音频信号进行取样，得到振幅信息，其中，该振幅信息可有多个振幅值组成。在一实施例中，以3s为例，3s时长内播放的音源中，对应得到的音频信息中的多个振幅值，记录获取的每个振幅值，确定其中的最大振幅以及所有振幅的平均振幅。
在另一实施例中，当检测音源播放时，每隔预设时间(如1s、3s或10s)确定一次预设长度的音频信息，或者实时的，对音频信息的每一帧的振幅进行确定。例如，所述获取所述音源的音频信息包括：所述获取所述音源的预设长度的音频信息包括：获取所述音源的预设长度的音频帧信息；相应的，确定所述预设长度的音频信息中的最大振幅和平均振幅包括：依据所述音频帧信息确定所述预设长度的音频信息中的最大振幅和平均振幅。在一实施例中，当检测到音源播放时，对音源文件进行解析得到音频帧序列，确定预设长度的音频信息下每一帧确定对应的振幅，进而确定最大振幅和平均振幅。
在步骤S103中，依据所述最大振幅和所述平均振幅确定振幅调节系数，依据所述振幅调节系数对所述音源的振幅进行调节。
在一实施例中，可根据最大振幅和平均振幅确定固定的振幅调节系数，或者确定不同的振幅调节系数，再根据具体的音源振幅的大小进行分配以进行振幅调节。在对音源的振幅进行调节的过程中，可通过对音源文件进行解析，对得到的音频数据中的表征振幅信息的数据进行修改，修改完毕后再进行封装，当缓冲到对应的音源文件并被播放时音源的振幅相应的已被增大；还可以是，在音源播放的解码过程中，通过对得到的数字音频信号进行分析得到振幅数据，将该振幅数据乘以对应的调节系数以改变振幅大小，进而对音源的音量进行调节。由此，实现了不改变终端设备系统原有音量的前提下对音源音量的大小进行了调节，调节过程可以在音源文件未进入缓冲区前，以减少播放负载，也可以是针对缓冲区中的音源内容进行调节以提高调节效率。
在另一实施例中，对音源的每一帧的振幅大小进行调节。例如，调节过程中针对每一帧的振幅大小的不同分配不同的振幅调节系数以进行对应调节，在一实施例中，具体对应关系可以如下表所示：
表1
振幅 调节系数
大于-3db或小于-50db 1
小于-10db且大于-50db 2
小于-3db且大于-10db 1.5
如表1所示，当音频帧的振幅大于-3db或小于-50db时，不对其增益进行调节；当振幅小于-3db且大于-10db时，振幅为高振幅区，为其分配增益系数为1.5，当振幅小于-10db且大于-50db时，为中振幅区，为其分配振幅系数为2以显著提高该部分振幅的振幅大小。
在一实施例中，所述依据所述最大振幅和所述平均振幅确定振幅调节系数包括：如果所述最大振幅和所述平均振幅的差值满足预设条件，则依据所述最大振幅和所述平均振幅确定振幅调节系数。在一实施例中，当最大振幅和平均振幅差值较大时(如0.2db)，为了避免播放到较大振幅的音源时音量较大，对较高的振幅进行调节以的降低音量。在一实施例中，若最大振幅和平均振幅之差不满足预设条件，即相差不大，则不对音源的振幅进行调节。
图2是本申请实施例提供的另一种音量调节方法的流程图，在一实施例中，所述依据所述最大振幅和所述平均振幅确定振幅调节系数包括：依据所述最大振幅和所述平均振幅的差值确定第一振幅调节系数；相应的，所述依据所述振幅调节系数对所述音源的振幅进行调节包括：依据所述第一振幅调节系数，对所述音源中大于第一预设阈值的振幅进行调节。如图2所示，技术方案包括步骤S201，步骤S202以及步骤S203。
在步骤S201中，当检测到终端设备进行音源播放时，获取所述音源的预设长度的音频信息。
在步骤S202中，确定所述音频信息中的最大振幅和平均振幅。
在步骤S203中，依据所述最大振幅和所述平均振幅的差值确定第一振幅调节系数，依据所述第一振幅调节系数，对所述音源中大于第一预设阈值的振幅进行调节。在一实施例中，依据最大振幅和平均振幅的差值确定第一振幅调节系数的关系如下表：
表2
最大振幅和平均振幅的差值 调节系数
大于0.4db 0.4
大于0.3db且小于0.4db 0.6
大于0.2db且小于0.3db 0.8
其中，该第一预设振幅阈值可以是-2db，即将大于第一振幅阈值的振幅大小乘以对应的调节系数以进行振幅衰减降低音量。由此，对音源中振幅较大的部分进行合理衰减以避免听感突兀，提高了音源的播放效果。
图3是本申请实施例提供的另一种音量调节方法的流程图，在一实施例中，在所述依据所述最大振幅和所述平均振幅的差值确定第一振幅调节系数之后，还包括：依据所述平均振幅确定第二振幅调节系数；相应的，所述依据所述振幅调节系数对所述音源的振幅进行调节还包括：依据所述第二振幅调节系数，对所述音源中小于第二预设阈值且大于第三预设阈值的振幅进行调节，所述第二预设阈值小于第一预设阈值。如图所示包括步骤S301，步骤S302，步骤S303以及步骤S304。
在步骤S301中，当检测到终端设备进行音源播放时，获取所述音源的预设长度的音频信息。
在步骤S302中，确定所述音频信息中的最大振幅和平均振幅。
在步骤S303中，依据所述最大振幅和所述平均振幅的差值确定第一振幅调节系数，依据所述第一振幅调节系数，对所述音源中大于第一预设阈值的振幅进行调节。
在步骤S304中，依据所述平均振幅确定第二振幅调节系数，依据所述第二振幅调节系数，对所述音源中小于第二预设阈值且大于第三预设阈值的振幅进行调节。
其中，所述第二预设阈值小于第一预设阈值。在一实施例中，依据所述平均振幅确定第二振幅调节系数。在一实施例中，平均振幅和第二振幅调节系数的对应关系如下表：
表3
平均振幅 调节系数
-25db 1.2
-20db 1.5
-15db 1.8
在一实施例中，该第二预设阈值可以是-30db，第三预设振幅阈值可以是-50db。当确定出的音源振幅小于第二预设阈值且大于第三预设阈值时，按照表3对应的调节系数对满足条件的振幅进行调节。
由上述可知，依据音源的平均振幅的大小确定对应的调节系数，平均振幅越大对应的调节系数越高，对满足条件的(小于第二预设阈值且大于第三预设阈值)的振幅按照该调节系数进行调节，将音源中较低的音量部分进行音量的提高，改善音源播放播放过程中播放效果，避免用户手动进行音量调节，可以提高音量调节效率。
图4是本申请实施例提供的另一种音量调节方法的流程图，在一实施例中，在所述依据所述最大振幅和所述平均振幅确定振幅调节系数之前，还包括：确定所述终端设备播放器件的阻抗值；相应的，所述依据所述最大振幅和所述平均振幅确定振幅调节系数包括：依据所述阻抗值、所述最大振幅和所述平均振幅确定振幅调节系数。如图所示包括步骤S401至步骤S406。
在步骤S401中，当检测到终端设备进行音源播放时，获取所述音源的预设长度的音频信息。
在步骤S402中，确定所述音频信息中的最大振幅和平均振幅。
在步骤S403中，确定所述终端设备播放器件的阻抗值。
在在一实施例中，可通过功放芯片检测终端设备中安装的播放器件(如：扬声器)的阻抗值，还可以是通过物理方式检测播放器件的阻抗。
在步骤S404中，依据所述阻抗值、所述最大振幅和所述平均振幅确定第一振幅调节系数。
在一实施例中，在上述实施例中依据最大振幅和平均振幅的基础上，结合步骤S403确定的终端设备播放器件的阻抗值共同确定第一振幅调节系数。在一实施例中，该阻抗值越大对应的共同确定的第一振幅调节系数越大。例如，假设播放器件的标称阻抗值为x，通过检测得到的阻抗值为1.2x，则相应的第一振幅调整系数可以是仅通过最大振幅和平均振幅确定的振幅调节系数的1.2倍以作为最终确定的振幅调节系数。
在步骤S405中，依据所述第一振幅调节系数，对所述音源中大于第一预设阈值的振幅进行调节。
在步骤S406中，依据所述平均振幅确定第二振幅调节系数，依据所述第二振幅调节系数，对所述音源中小于第二预设阈值且大于第三预设阈值的振幅进行调节。
由上述可知，在对音源的振幅进行调节过程中，引入播放器件的阻抗值作为确定振幅调节系数的参量之一，可以避免播放器件随播放时长的增加阻抗值越来越高进而对正常播放过程中的音量大小产生影响的情况，使得调节后的音量大小更加符合用户需求，提高音量调节效果。
图5是本申请实施例提供的另一种音量调节方法的流程图，在一实施例中，在所述依据所述最大振幅和所述平均振幅确定振幅调节系数之前，还包括：确定所述终端设备播放器件的噪声值；相应的，所述依据所述最大振幅和所述平均振幅确定振幅调节系数包括：依据所述噪声值、所述最大振幅和所述平均振幅确定振幅调节系数。如图所示包括步骤S501至步骤S506。
在步骤S501中，当检测到终端设备进行音源播放时，获取所述音源的预设长度的音频信息。
在步骤S502中，确定所述音频信息中的最大振幅和平均振幅。
在步骤S503中，确定所述终端设备当前所处环境的噪声值。
在一实施例中，可通过终端设备安装的麦克风采集当前所处环境的噪音以确定对应的噪声值。
在步骤S504中，依据所述噪声值、所述最大振幅和所述平均振幅确定第一振幅调节系数。
在一实施例中，在上述实施例中依据最大振幅和平均振幅的基础上，结合步骤S503确定的终端设备当前所处环境的噪声值共同确定第一振幅调节系数。在一实施例中，该噪声值越大对应的共同确定的第一振幅调节系数越大。例如，假设终端设备在安静环境下的噪声值为y，终端设备处于户外或嘈杂环境中时，确定的噪声值为1.2y，则相应的第一振幅调整系数可以是仅通过最大振幅和平均振幅确定的振幅调节系数的1.2倍以作为最终确定的振幅调节系数。需要说明的是，还可将阻抗值、噪声值、音源的最大振幅和平均振幅共同确定音源的振幅调节系数。
在步骤S505中，依据所述第一振幅调节系数，对所述音源中大于第一预设阈值的振幅进行调节。
在步骤S506中，依据所述平均振幅确定第二振幅调节系数，依据所述第二振幅调节系数，对所述音源中小于第二预设阈值且大于第三预设阈值的振幅进行调节。
由上述可知，在对音源的振幅进行调节过程中，考虑了噪声对终端设备音量的影响，将确定的噪声值作为确定振幅调节系数的参量之一，使得调节后的音量大小更加符合用户需求，提高音量调节效果。
图6是本申请实施例提供的另一种音量调节方法的流程图，在一实施例中，在依据所述振幅调节系数对所述音源的振幅进行调节之后，还包括：依据所述振幅调节系数确定对应的音量调节信息；依据所述音量调节信息对所述终端设备当前的音量进行调节。如图所示包括步骤S601至步骤S604。
在步骤S601中，当检测到终端设备进行音源播放时，获取所述音源的预设长度的音频信息。
在步骤S602中，确定所述音频信息中的最大振幅和平均振幅。
在步骤S603中，依据所述最大振幅和所述平均振幅确定振幅调节系数，依据所述振幅调节系数对所述音源的振幅进行调节。
在步骤S604中，依据所述振幅调节系数确定对应的音量调节信息，依据所 述音量调节信息对所述终端设备当前的音量进行调节。
在一实施例中，根据振幅调节系数确定对应的音量调节信息。在一实施例中，当振幅调节系数大于1时，则确定对应的音量增大信息，当振幅调节系数小于1时，则确定对应的音量减小信息。例如，在一实施例中，该音量增大或音量减小的信息为对应的目标音量值。在一实施例中，终端设备由静音到最大音量总共分为18个可调等级，每个等级对应一个音量值，该音量减小信息对应的目标音量值可以是3或4，该音量增大信息对应的目标音量值可以是14或15，当确定出的音源振幅偏小时，则相应的将音量值增大至14或15，当确定出的音源振幅偏大时，则相应的将音量值减小至3或4。在另一实施例中，该音量增大或音量减小的信息为对应的音量改变值。在一实施例中，终端设备由静音到最大音量总共分为18个可调等级，每个等级对应一个音量值，该音量增大信息和音量减小信息对应的音量改变值为3，例如，当前终端设备的音量值为10，当需要增大音量信息时，则在当前音量值的基础上增加3即采用第13级音量进行声音播放，当需要减小音量信息时，则在当前音量值的基础上减小3即采用第7级音量进行声音播放。在一实施例中，在对终端设备的音量进行调节之前，还包括：确定该音源的播放时间，当播放时间大于预设时间时，如播放时间为30s，则采用依据所述音量增大信息或音量减小信息中的音量改变值对所述终端设备当前的音量值进行调节的方式，由此提高音量调节效率，降低终端设备的能耗。
由此，在对音源的振幅进行调节的基础上，适应性的对终端设备的播放音量进行调节，可以增强调节效果，使得音源播放过程中的音量更加适中，符合用户需求。
